Hi,

I just had a new porcelain crown installed (tooth #10) After it's permanently cemented I noticed that the tooth is significantly shorter than its symmetrical counterpart, creating a visible gap between the upper and lower teeth, so of course I want it redone. Is there a risk-free way of removing a permanently cemented crown? My dentist says that since the tooth inside is weak (has a root canal) there is a big risk of breaking it while trying to cut the crown. How good is the Richwil crown removal stuff?

Any opinion from you pros out there is appreciated.

Thanks,

Richwill is probably less risky than most other commonly used methods. But in my experience it mostly doesn't work, esp. with anterior crowns.

There is no risk-free method, either for the crown or the tooth. But any method that tries to take the crown off in the long axis of the tooth will be less likely to fracture the tooth.

I always found it less risky to cut a crown off. With care, a diamond bur will remove the procelain leaving the metal framework. With care the metal framework can be cut, getting to the cement without harming the tooth. At that point the crown easily comes off, and does so with the least amount of trauma to the patient and the tooth.

And with an endo tooth there is not worry about pulpal damage from this.
